Abstract
The utility model relates to the technical field of high-pressure well opening tools, in particular to a clamping hoop connecting type cement head which comprises a body assembly, a high-pressure manifold assembly and a clamping hoop. The high-pressure manifold assembly is fixedly arranged on the body assembly. The lower end of the body assembly is fixedly provided with a clamping ring. An annular boss is arranged on the outer wall of the clamping ring. A clamping groove corresponding to the boss is formed in the inner wall of the upper portion of the clamping hoop. The clamping hoop is fixedly arranged on the outer side of the clamping ring, the boss is placed in the clamping groove, and an annular clamping table is fixed on the inner wall of the lower portion of the clamping hoop. The clamping hoop connecting type cement head is reasonable and compact in structure and convenient to use, the strict requirement that the buckle type of a sleeve and the buckle type of a well cementation cement head are consistent is of no need, a sleeve connecting hoop in any buckle type and the body assembly in the same size can be connected for carrying out well cementation, well cementation facility cost can be effectively lowered, and workload of cement head maintaining can be lowered.
Description
Technical field
the utility model relates to high-pressure well mouth technical field of tools, is a kind of clamp connection type cementing head.
Background technology
well cementation is a very important link in whole drilling process, and can the quality of cementing quality directly have influence on a bite well and bore smoothly and reach target zone and carry out normal mining operations.When in conventional cementing, cementing cement head connects with bunch tube, button-type must be consistent with sleeve pipe button-type, in the well cementing operation of different sleeve pipe button-types, just need carry the cementing cement head adapting with it and complete construction operation, cause cementing operation unit must prepare the cementing head of multiple button-type, not only increase well cementation facility cost, also increased the workload of employee to cementing head maintenance.
Summary of the invention
the utility model provides a kind of clamp connection type cementing head, overcome the deficiency of above-mentioned prior art, it can effectively solve and in current well cementing operation, necessarily require the consistent and problem that facility cost is high, the workload of cementing head maintenance is large that causes cementing the well of the button-type of sleeve pipe button-type and cementing cement head.
the technical solution of the utility model realizes by following measures: a kind of clamp connection type cementing head, comprises body assembly, high pressure pipe joint assembly and clip; On body assembly, be installed with high pressure pipe joint assembly, the lower end of body assembly is installed with snap ring, on the outer wall of snap ring, there is annular boss, in the upper inside wall of clip, there is the draw-in groove corresponding with boss, in the outside of snap ring, be installed with clip and make boss be positioned at draw-in groove, in the lower inner wall of clip, be fixed with annular Ka Tai.
the further optimization and/or improvements to above-mentioned utility model technical scheme below:
on above-mentioned clip inwall between snap ring and card platform, be installed with seal.
above-mentioned clip comprises front clip and rear clip, front clip and rear clip are semicircle annular, in the upper inside wall of front clip and rear clip, all there is the annular draw-in groove corresponding with boss, on the lower end inwall of front clip and rear clip, be all fixed with annular Ka Tai, hinged between front clip and the left end of rear clip, between front clip and the right-hand member of rear clip, be installed with locking device.
hinged by hinge between above-mentioned front clip and the left end of rear clip.
the utility model reasonable and compact in structure, easy to use, not needing to be strict with sleeve pipe button-type must be consistent with the button-type of cementing cement head, no matter the casing coupling of which kind of button-type of every same size can be connected and implement well cementation with body assembly, can effectively reduce the workload of well cementation facility cost, the maintenance of minimizing cementing head.
Accompanying drawing explanation
accompanying drawing 1 is looked half section structural representation for the master of the utility model most preferred embodiment.
coding in accompanying drawing is respectively: 1 is body assembly, and 2 is high pressure pipe joint assembly, and 3 is seal, and 4 is snap ring, and 5 is boss, and 6 is draw-in groove, and 7 is Ka Tai, and 8 is front clip, and 9 is locking device, and 10 is hinge, and 11 is rear clip.
The specific embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this clamp connection type cementing head comprises body assembly 1, high pressure pipe joint assembly 2 and clip; On body assembly 1, be installed with high pressure pipe joint assembly 2, the lower end of body assembly 1 is installed with snap ring 4, on the outer wall of snap ring 4, there is annular boss 5, in the upper inside wall of clip, there is the draw-in groove corresponding with boss 56, in the outside of snap ring 4, be installed with clip and make boss 5 be positioned at draw-in groove 6, in the lower inner wall of clip, being fixed with annular card platform 7.In the middle of high pressure pipe joint assembly plays, connecting media and control action, connected cementing equipment and body assembly, and can control passing through and closing of fluid; The upper end of clip and snap ring 4 can firmly link together by boss 5 and draw-in groove 6, the card platform 7 of the lower end of clip can be connected the upper end of casing coupling with body assembly 1 fast, as long as measure-alike, no matter the casing coupling of which kind of button-type can be connected with body assembly 1, overcome in existing conventional cementing the difficult problem that when cementing cement head connects with bunch tube, button-type must be consistent with sleeve pipe button-type.
can according to actual needs, above-mentioned clamp connection type cementing head be made further optimization and/or improvements:
as shown in Figure 1, on the clip wall between snap ring 4 and card platform 5, be installed with seal 3.After the upper end of casing coupling and body assembly 1 link together, seal 3 can guarantee the sealing connecting between it.
as shown in Figure 1, clip comprises front clip 8 and rear clip 11, front clip 8 and rear clip 11 are semicircle annular, in the upper inside wall of front clip 8 and rear clip 11, all there is the annular draw-in groove 6 corresponding with boss 5, on the lower end inwall of front clip 8 and rear clip 11, be all fixed with annular card platform 7, hinged between front clip 8 and the left end of rear clip 11, between front clip 8 and the right-hand member of rear clip 11, be installed with locking device 9.Clip comprises front clip 8 and rear clip 11, facilitates the installation and removal of casing coupling, effectively increases work efficiency, and locking device 9 can guarantee the fastness of clamp connection casing coupling and body assembly 1, and locking device 9 can adopt the bolt of existing known technology.
as shown in Figure 1, hinged by hinge 10 between front clip 8 and the left end of rear clip 11.
above technical characterictic has formed most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease according to actual needs non-essential technical characterictic, meets the demand of different situations.
